Ni/n-SiO2 compositional coatings were electrodeposited by brush-plating with pulse-reverse current. Morphology, hardness, and tribological properties of the coatings were investigated and compared with those of Ni and composite coatings electrodeposited by brush-plating with direct current. The test results obtained indicate that Ni/n-SiO2 composite coatings electrodeposited by brush-plating with pulse-reverse current, because of the pulse-reverse current and the nano powders, possesses the fine crystal grains, high hardness and low friction coefficient, so it is a better wear-resistant coatings.
